I had just gotten back from college and my brother who I hadn't seen for awhile had really grown into a young man. I thought that he must be jacking off by now because I would hear heavy breathing and some other noises at night. We live in an old farmhouse so the walls are pretty thin and parts have thin and tiny cracks that you can barely see through but still see through nonetheless. I was going to take a bath and my brother, whose room is across from the bathroom, raced upstairs to his room. I knew there was a crack in his room and I thought I would have a little fun. I got naked and sat on the toilet seat with my legs wide open and I started to play. But not to long -- I wanted to save some for the bath. I took my bath and went to my room when my brother busts in panting and I could see his erection in his pants. He said, 'Help me please.' I guess he wasn't jacking off after all. I had to help him before he burst so I made a deal. 'As long as you can help me I'll teach you what to do,' I said. He agreed and I showed him what to do. Slowly I started to go up and down his penis, which was pretty big for his age (14). Then I went faster and told him to put his hand there too. He did and he came quickly. He then put his hand into my twat, which was wet, and fingered me.
Well I'm wet just typing this and my brother is standing over my shoulder. So bye-bye.
